Nowadays, modern data centers consist rows and rows of server & network racks. Within the racks, there are high powered servers which generate lots of heat. The number one problem in a data center is HEAT nowadays. Thus, monitoring and managing the temperature inside the rack to the manufacturer’s recommended operating environment is a big challenge. Every electronic equipment will operate best as long as the temperature does not exceed manufacturer’s specified operating environment. We all know that. However, the current method of doing show is cumbersome & messy. It has lots of constraints. The whole problem points to the basis that it is a ‘wired’ solution. Wired technology is becoming a ‘sunset’ technology. The data center can do with less or no wires. The current data center is already congested with wires running below the raised floors, along cable trays and/or conduits. It is very messy. It is difficult to manage. It has no investment protection. Thus, it is a big problem for wired technology.
